Hi,

I’ve got a model i.e. Ticket, which has it’s own edit page. There’s  
also i.e. Report controller which has a view where I can edit i.e. one  
field of Ticket and Project controller where I can edit other field of  
Ticket object.

The question is: how to use only one update method in Ticket  
controller and write redirect part in a simple way, so it will  
redirect back to the action from which it was called (or execute some  
rjs)?

Should I send some additional parameter or use HTTP\_REFERER and make  
case statement for redirecting/rendering rjs? Is there some simpler  
way?

Regards

redirect\_to :back will do the referrer thing for you.

Thanks.

This will work for html, s half of the problem is gone 🙂 But what  
about ajax request where I need to render specific rjs file?
